LEMUEL ROBERT HOPTON, OF PEAINFIELD, NEW JERSEY, ASSIGNOR TO THE ENOS COMPANY, OF YORK.

NEW YORK, N. Y., A CORPORATION OF NEW lNOANDESCENT-LIGHTING FIXTURE.

SPECIFICATION forming part of Letters Patent No. 786,812, dated April 11, 1905.

Application filed $eptember 10, 1904. flerial No. 223,972.

T at whom, it may concern.-

Be it known that I, LEMUEL ROBERT Hor- TON, a citizen of the United States, residing at Plainfield, Union county, and State of New Jersey, have invented certain new and useful Improvements in Incandescent-Lighting Fixtures, of which the following is a full, clear, and exact description.

My invention relates'to improvements in incandescent-gas-lighting fixtures.

The object of my invention is to provide a simple, economical, and eflicient construction which may be artistically designed and arranged in a gas-fixture. I have sought to construct the parts in such a way that they may be readily assembled or disassembled, as

' occasion mayrequire, and so that the provisions for the admission of air and the regulation of gas may be properly reached. The parts are adapted for the simplest as well as the most elaborate ornamental treatment.

The invention consists in improvements the principles of which are illustrated in the accompanying sheet of drawings.

Figure 1 is a vertical section and elevation of a gas-burner embodying improvements of my invention, the burner-head and globeholder, however, being just in position for assembling. Fig. 2 is a plan view of the burn erhead and globe-support. Fig. 3 is a plan view of the socket and part of the casing. Fig. 4 is a side elevation of the part of the casing not shown in Fig. 3.

1 indicates a tip adapted to screw onto a gas-pipe or fixture-arm and having a screwthreaded post with a gas-passage and a needle or conical valve-seat.

2 is an adjustable member or valve having an opening in the top adapted to coact with the Valve-seat for the regulation of the admission of gas.

3 is a set-nut which coacts with the valve portion 2 for looking it in the desired position relatively to the tip 1.

4: is the burner-tube having air-inlets 5 ad- The gas and air are mixed within the body of the tube 4.- and injected upward to the flame. A casing surrounds a part of the burner-tube and in the preferred form is composed of the base part 6 and the body part 7. This case has a series of openings 8 near the base for the admission ofair to the burner. struction a yoke having two arms 9 9 is employed, at the upper ends of which the screws 10 10 are seated. The body of the casing 7 having two slots like 11, forming, with the screws 10 10, bayonet-joints, is adapted to be readily attached to the base of the casing or removed therefrom when desired. At the upper end of the burner-tube is a socket 12, which has a flange 13 just below but fitting closely within the upper end of the casing.

This forms a closed chamber around a part of the burner-tube and also forms an annular space inside the top of the casingbetween the casing and the socket.

In the preferred con- 14 is a collar formingthe base ofthe burnerhead.

15 is an annular member which is securely attached to the collar 14:, the two being adapted to slip on over the socket 12 and fit within the annular space at the-top of the casing.

16 is a tubularmember constructed, preferably, of sheet-mica, which forms an insulating medium to prevent the heat of combustion being transmitted back to the other parts 21 is a flange which is attached to the socket 14. by a plurality of arms and forms a shade or globe holder orsupport.

22 22 are clamp-screws.

23 is a globe.

The head of the burner,

together with the globe-support, isremovable, as shown.

means of connection preferably consists of a pair of projections, like projection 2 adapted to coact with a pair of depressions, like 25, in the socket 12, affording bayonet-joints. The joint is, however, concealed by the upper edge of the casing 7.

The advantages of this construction in addition to the objects desired, as set forth above, Will be apparent to those Who are skilled in the art of incandescent-gas lighting.

What I claim is- 1. In an incandescent-gas-lighting fixture, the combination of a burner tube having means for the admission of gas and air, a casing surrounding a portion thereof, a socket carried by said tube of smaller diameter than said casing and leaving an annular space inside thereof and a burner-head having a collar with means of connection with said socket inside said annular space.

2. In an incandescent gas-burner, the combination-of a burner-tubehaving means for the admission of gas and air, a large cylindrically-formed casing surrounding and spaced apart from a portion of said tube with a socket at the upper end of said tube having a plurality of indentations forming bayonet-joints Within an annular space at the top of said easing and a globe-supporting member having a plurality of indentations adapted to removably coact With said bayonet-joints inside said annular space.

8. In an incandescent gas-burner, the combination of a burner-tube having means for the admission of air and means for the admission and regulation of gas, a cylindrical casing surrounding and spaced apart from a portion of said tube, a socket having bayonetlike recesses, a globe-supporting member having projections adapted to removably coact therewith, an insulating-tube carried by said member, and a burner-cap having a plurality of outlets, said cap being secured to said insulating-tube and spaced apart vertically from the other portions of said globe-supporting member.

4. In an incandescent gas-burner, the combination of a burner-tube having air-inlets 7 portion having a plurality of openings for the admission of air, said casing forming an airchamber of substantlal size around a portion of said burner-tube, and a burner-howl of cylindrical form surrounding but spaced apart from the remainder of said tube and removably carried thereby.

6. In an incandescent gas-burner, the combination of a burner-tube having means for the admission of gas and air, a casing surrounding a large part of said tube and comprising a conveXly-curved base having a series of perforations for the passage of air and a substantially cylindrical body portion removably secured thereto and a detachable globe-supporting member and burner-head.

7 In an incandescent gas-burner, the combination of a burner-tube having means for the admission of gas and air, a cup-shaped member carried by said tube, a substantially cylindrical shell removably secured to said cup-shaped member and spaced apart from said tube and forming a substantial air-chamber, a burner-cap and an insulating-tube supporting said cap and vertically separating it from the other parts of said burner and said air-chamber.

8. An incandescent gas-burner colmn-ising the combination of a burnertube having means for the admission of gas and air, a casing surrounding a portion of said tube but spaced apart therefrom, a combined bu rner-head and shade-holder having a depending collar removably carried inside the rim of said casing, said burner-head including a tubular member having an outlet for the combustible mixture and means for thermally insulating the outlet from said casing:

9. In an incandesceut-lighting fixture, the combination of a burner-tube having means for the admission of gas and air, a casingsurroumling a portion thereof, a socket carried by said tube of smaller diameter than said easingand leaving an annular space inside thereof and a burner-head havinga collar with means of connection With said socket inside said annular space, and means for thermal insulation inserted between the outlet of said burner-heml and said casing.

10. In an incandescent gas-burner, the combination of a burner-tube having air-inlets near the base, a gas-inlet adjacent to said airinlets, a substantially cylindrical casing having a base portion having a plurality of openings for the passage of air, said casing forming a substantial air-cushioning chamber, a globe-supporting member detachably supported by said tube, and thermal insulating means inserted between the outlet of said burner and said chamber and casing.

11. In an incandescentgas-burner, the combination of a burner-tube having means for the admission of gas and air, a cup-shaped member carried by said tube, a substantially cylindrical shell removably secured to said cupshaped member and spaced apart from said tube and forming a substantial air-clnm1ber, a

IIC

burner-cap and thermal insulating means inserted between said cap and the other parts of said burner and said air-chamber.

12. An incandescent gas-burner comprising the combination of a burner-tube with means for the admission of gas and air, a casing of substantial. size carried by said tube, and

spaced apart laterally therefrom, a tubular member movably carried adjacent the rim of I 0 said casing and forming part of a burner-head,

and provided with an outlet for the combustiblemixture, and a globe-supporting member carried by said tubular member and removable therewith.
